以4-硝基邻苯二腈(1)、3-硝基邻苯二腈(4)和2-异丙基-5-甲基苯酚(2)为起始化合物,在氢氧化锂的作用下,经亲核取代反应生成了相应的邻苯二腈衍生物(3)和(5).以化合物(3)和(5)为前体,在催化剂1,8-二氮杂二环[5,4,0]十一碳-7-烯(DBU)的作用下发生环合四聚反应,得到了具有优良溶解性的四取代酞菁,铟氯酞菁和钛氧酞菁6a-6c,7a-7c.并分别用氢核磁、质谱、紫外可见光谱和元素分析确认了这些化合物的结构.
Phthalocyanines (Pcs), Chloroindium phthalocyanines (ClInPcs) and oxotianium phthalocyanines (OTiPcs) 6a-6c,7a-7c were generated by cyclotetramerisation of phthalonitrile derivatives (3) and (5) in the presence of 1,8-diazabicyclo[5. 4. 0] undec-7-ene (DBU) as the catalyst. Taking 4-nitrophthalonitrile (1) or 3-nitrophthalonitrile (4) with 2-isopropyl-5-methylphenol (2) as the starting materials, the corresponding phthalonitrile derivatives (3) and (5) were prepared. All the compounds were characterized by ^1H NMR,MS,UV/Vis and elemental analysis,which were consistent with the proposed structures.
